(Last September, Skyhook sued Google, saying that Google was basically preventing it from doing business by forcing its customers -- Motorola and Samsung -- to stop using Skyhook software in their Android phones. More here and here.)

Lots of emails between Googlers talking about their location service versus Skyhook's. It's an interesting glimpse into how Googlers communicate with each other. (Including a "Thread-kill" email when they realized they should stop making a paper trail about this issue.)
